Fiz as modificações do curso:
postgres
spring.datasource.url=jdbc:postgresql://localhost:5432/logsdb spring.datasource.username=alura spring.datasource.password=nJ6vsW37rCd1v88 spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
Mas ainda aparece o problema : { "timestamp" : "2023-01-19 15:24:00.798", "level" : "ERROR", "thread" : "restartedMain", "logger" : "org.springframework.boot.SpringApplication", "message" : "Application run failed", "context" : "prod", "exception" : "org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]\n\tat
